I wrote a Face detection script with the LBPH algorithm (in Python) cv2.face.createLBPHFaceRecognizer().
My problem is any other person that the algorithm is not trained on, returns me my number. (If it is me it returns 1 but if it's an other person it does the same). So I want to know what I can do, I read something about threshold but I don`t know how to use it and I read about a bug Link to bug. But I don't know how to rebuild the stuff. So I want to know what you recommend me, threshold or rebuilding, or anything else.
So I had a wrong indentation in my code. I returned the number for training with the python return command and so it stoped looping and only trained one number and image.
